The High-Luminosity Large Hadron Collider (HL-LHC) project aims to crank up the performance of the LHC in order to increase the potential for discoveries after 2027. The objective is to increase luminosity by a factor of 10 beyond the LHC’s design value. The project is led by CERN with the support of an international collaboration of 29 institutions in 13 countries.
Luminosity is an important indicator of the performance of an accelerator: it is proportional to the number of collisions that occur in a given amount of time. The higher the luminosity, the more data the experiments can gather to allow them to observe rare processes.
Nb-Ti, MgB2 and ReBCO: a combination of conventional and novel superconductors for the powering of the HL-LHC magnets. Demo 2 and Demo 3 demonstration systems were successfully qualified at CERN in 2020.
